PA Hilton - Model A660 -Air Conditioning Laboratory Unit

The base unit comprises a variable speed radial acting axial flow fan discharging into a 250mm square duct with steam humidifier, electrical pre-heaters, direct expansion cooling coil/de-humidifier, electrical re-heaters and orifice plate for airflow measurement. Air-cooling is provided by vapour compression refrigeration system with pressure, temperature and refrigerant flow measurement. This allows the construction of a full cycle diagram and the balancing of refrigerant system energy balance against the airside energy transfer.

• Psychrometric condition measured before and after each process by high precision wet and dry bulb sensors with 0 to 100% RH measurement capability.
• Airflow is adjustable to at least 0.14m3/s.
• Switchable heating up to 4kW.
• Switchable steam injection up to 5kW electrical equivalent.
• Cooling is by a fully instrumented vapour compression cycle with nominally 2kW capacity.
